SANITARY WATER-CLOSET.

Specification of Letters Patent.

Patented Aug. 31, 1909.

Application filed April 8, 1907. Serial No. 366,282.

To all whom it may concern:

Be it known that I, SHEFFIELD SMITH, a citizen of the United States,residing at Providence, iii the State of Rhode Island, have invented anew and useful Improvement in Sanitary Water-Closets, of which thefollowing is a specification.

The nature of my invention consists in the combination with the seat ofa watercloset, of a means :for retaining the excreta in a receptacleuntil the occurrence of a predetermined. event, upon which occurrencethe contents of the said receptacle will be automatically discharged.

It also consists of means for heating the said excreta to a degreesufficient todestroy the life of the contained erms before it isdischarged from the receivingreceptacle.

It also consists in means for automatically efl'ecting.the discharge ofthe receiving receptacle upon the attainment of the proper de ree oftemperature.

t also consists in means effecting ceptacle upon the event of thecompletion of an electric circuit.

In the accompanying drawings :-Figure 1 represents an axial section of awatercloset provided with my improvement. Fig. 2, represents an axialsection of the sterilizing receptacle when turned to discharge thecontents thereof. 'Fig. 3, re resents a section taken in the line 3, 3,of l ig. 1. Fig. 4, refpresents a detail view of the turning joint 0 forautomatically sterilizing receptacle, broken away tov show itsconstruction. Fi detail axial section as in modification in the heatingmeans.

In the drawings, A, re resents the watercloset, B, the floor to which itis secured, and O, the hinged seat; D, is an extension sleeve inclosingthe lower end of the closet A, to which it islsecured, the said sleevebe ing provided with the projecting arms E,

. 5, represents a to which the receptacle 1 is hinged,the said recetacle being operatively connected with the iinged seat C, by means ofthe rod G, which is provided with the slot H, and jointed togtlie arm I,which latter is attached to the under side of the rear of the seat, andby Ilieiiilfiof the arm I, the said seat is ed to thescloset A, wherebythe seatO, arm I will serve to form a The receptacle F, is

rovided at it's in- N, adapted for and the connected hand-operatedlever. made in bowl form, and

nor side with the coiled pipe receptac e ,shown in Figs. 1 and thedischarge of the receiving re;

ig. 1, showing a the entrance of either steam or of hot water, the saidipe terminating at the trap J. The F, is held in its raised position as5, by means of the s iring actuated catch K, which en ages with Le lugL, upon the sleeve D, an is drawn ack to release the rece tacle by meansof ,the electromagnet M, w ich is attached to the outer side of the saidreceptacle. The action of the elcctromagnct to cause the withdrawal ofthe catch K, fronitlie lu L, in order to empty the receptacle F545elected by means 01 an electric cpntactwith the magnet wire S, effectedu ii tli'etxpansion of the diaphragm a, of t e trap J, by the ac uiredheat of the contents of-the receptac e F. And when the said catch hasbeen withdrawn the receptacle will drop by gravity from the'fpositionshown in Fig. 1, to the'position shown in Fig. 2, and the heated excretatherein will be discharged.

The steam for heating the excreta in the receptacle'F, is caused to passfrom the supply pipe 0, through the hinge joint shown in longitudinalsection in Fig. 4. The

' arm Q, is attached to the hinge portion of the receptacle and firmlysecured thereto. by means of the pin It, and the outed end of the saidarm is provided with a stud I), which is held in the slot H, of the rodG thus forming a loose connection; so that when the hinged seat C, israised to the inclined position shown by the dotted lines the receptacle1, will, when required, be allowed to drop to the position shown in Fig.2. And when the seat C, is brought down to its proper position for use,the said receptacle will be brought up to the position shown in Figs. 1and 5, for the holding engagement of the catch K, with the lug L.

As shown in Figs. 1 and 2, the steam trap J, is located at the outerside of the receptacle, and the steam is to be heldin the pipe N, underpressure, but Fig. 5, represents the apparatus when the diaphragm a, isheld in contact with the excreta and is used only to cause thedisengagement of the receptacle the coils of the pipe N, are made open,but in prnc tics the spaces between the coils will be closed 11 true surace at its inner side.

I have described the principles involved so that the bowl will present ain the operation of my invention, together I? with an apparatus whichrepresents an embodiment thereof, but I desire to have it undin-stoodthat the ini rorcment may be can ried out by the emp oymcnt of variousdevices without departing from the spirit of my invention which ronsistsin the rt-ateniion of the excreta in a receiving receptacle forsterilization therein, with eventual auto matic discharge.

I. make no claim whatever to the combination with a bowl provided with agravity discharge orifice, of a receptacle or pan pivoted to close saidorifice, and means for admitting a heating fluid to heat the pan neitherdo I claim the combination of a water closet seat and a pivotedreceptacle for holding the excreta, with a steam passage extending tothe receptacle through the hinge joint, the same having been previouslyin rented by another.

I claim as my invention:

1. The combination with a water closet seat. of a swinging receptaclefor receiving the excreta. means attached to the said receptacle andswinging therewith for heating and sterilizing the excreta depositedtherein. and mean for automatically discharging the sterilized excretafrointhe receptacle.

The combination with a watercloeet seat. of a receptacle for receivingthe excreta, means for heating the excreta within the receptacle,a11dmeans for causing the discharge of the excreta u on the attainment ofthe required degree 0 heat.

3. The combination with a Water-closet seat, of a receptacle forreceiving the excreta, means for heating the excreta within thereccptacle, and electrical means for causing the discharge of theexcreta upon the attainment of the required degree of heat.

4. The combination with a ,water-closet seat, of a receptacle forreceiving the excreta, a steam pipe and trap for heating the excretaWithin the receptacle, and electric means operated by the action of thetrap for causing the discharge of the excreta upon the attainment of therequired degree of heat.

o. The combination of a waterwloset seat and a hinged receptacle forholding the excrcta with a catch f r holding the receptacle in itsreceiving position and meane for cans ing the electric withdrawal oi thecatch for discharging the contents of the receptacle.

6. The combination of a eater-closet seat and a hinged receptacle forholding the evcrota with means for holding the receptacle in itsreceiving poeition and a loos-e connection for causing the elevation ofthe receptacle whereby upon the reversal of the movement of theelevating means, the receptacle may at a predetermined proper time be allowed to drop to its discharging position without obstruction.

T. The combination of a Watencloset seat and a hinged receptacle forholding the excreta, wit h a catch for holding the receptacle inposition for receiving the excreta, and an electromagnet for withdrawingthe catch upon the event of a completion of the electric circuit.

8. The combination of a water closet seat. and a hinged receptacle forholding the ex.- creta, with a catch for holding the receptacle inposition for receiving the excreta, means for raising the receptacle toits catch-engaged position, and means for causing the automaticdisengagement of the receptacle at a. predetermined proper time.

9. In a sanitary water closet, the combination of a hinged receptaclefor holding the excreta, means for holdin the said receptacle inpositioirfor receiving the excreta, a hand-operated between the said.hand-0perated lever and the said hinged receptacle, whereby u on thereversal of the movement; of the sai lever, the receptacle may at anydetermined time be allowed to drop to its discharging position withoutobstruction. r
